Why do we use 3.14 when finding the area of a circle?

We use 3.14 as an approximation for the mathematical constant π (pi), which represents the ratio of a circle's circumference to its diameter. The formula for the area of a circle is A = πr², where r is the radius. Using 3.14 allows for easier calculations while still providing a reasonably accurate estimate of the area, especially in basic or educational contexts. For more precise calculations, π can be used in its more exact form or with more decimal places.
